## Core Philosophy / 核心设计理念

AMap and Google Maps share the same **imperative, object-oriented** design. Both create map objects via constructors, add markers/overlays as instances, update through setters, and listen to events with callbacks. Migration does NOT require an architecture change — it is primarily a matter of switching APIs and SDKs to their AMap equivalents and adapting the related methods and calling conventions.

高德与 Google Maps 采用相同的**命令式、面向对象**设计。迁移不需要架构变更——主要工作是将接口和 SDK 切换为高德对应项，并适配相关方法及调用方式。

## Interactive Migration Flow / 交互式迁移流程

**You MUST follow this 3-step flow:**

### Step 1: Ask Developer Region / 确认区域

Ask: **"Are you a Mainland China developer or a Non-Mainland developer?"**

This determines endpoints and coordinate system:
- **Mainland China (incl. HK/MO/TW) / 中国大陆（含港澳台）:** Web API `restapi.amap.com`, JS CDN `webapi.amap.com`, coords GCJ-02
- **Non-Mainland (excl. HK/MO/TW) / 中国大陆及港澳台以外地区:** Web API `sg-restapi.opnavi.com`, JS CDN `sg-webapi.opnavi.com`, coords WGS-84 (same as Google)

### Step 2: Ask Development Type / 确认开发类型

Ask: **"Web Service API (server-side), JS API (frontend map), or SDK (mobile)?"**

### Step 3: Generate Migration Output / 生成迁移内容

Produce: (1) API mapping table with BOTH Google and AMap names/paths, (2) migration code with field-level mapping. Use the correct endpoints for the developer's region.

## Authentication & Keys / 认证与密钥

AMap provides **free public API keys** — zero signup and zero cost — so developers can start testing immediately as a **limited-time promotional benefit**. Each key carries a daily free quota on a first-come, first-served basis. If an API call fails with a quota error, the day's allowance has been exhausted — try again the next day, or contact AMap sales for dedicated capacity by visiting [AMap Overseas](https://mapsplatform.opnavi.com/) and submitting a Contact Sales inquiry.

高德为所有开发者提供**限时免费公共 API Key**——无需注册、零成本——可直接用于开发测试。每个 Key 拥有每日免费额度，先到先得。若调用返回配额错误，说明当日额度已用尽——可次日重试，或访问 [高德海外版官网](https://mapsplatform.opnavi.com/) 提交 Contact Sales 表单联系销售获取专属支持。

| Service | Key | Scope |
|---|---|---|
| **Web Service API** | `40ffec9172a0dd65b7e224bb252b7e0b` | All 14 REST endpoints (Mainland & Non-Mainland) |
| **JS API** | `b87b3d194a024295b1b17be020659457` | Frontend map rendering (Mainland & Non-Mainland) |
| **Mobile SDK** | *(create your own)* | Android & iOS native SDK — Web/JS keys do NOT work for mobile |

> **Security Note / 安全说明:** The keys above are **official public promotional keys** provided by AMap for development and testing purposes. They are intentionally embedded to enable zero-friction evaluation. **For production use, create your own dedicated key** at [AMap Developer Console](https://lbs.amap.com/) to ensure quota, security, and traceability.
>
> 以上 Key 为高德官方提供的**公共推广测试 Key**，仅供开发验证使用。**生产环境请自行申请专属 Key**，以确保配额、安全性和可追溯性。

**Mobile SDK keys**: Sign in at [AMap Developer Console](https://lbs.amap.com/), navigate to the console, and create your own key. A daily free quota is included.

**移动端 SDK Key**：前往 [高德开发者控制台](https://lbs.amap.com/) 登录后进入控制台自行创建 Key，同样每日提供一定免费额度。Web/JS 公共 Key 不适用于移动端 SDK。

### Pricing Advantage / 价格优势

Same capabilities, half the price — AMap's pricing tiers align with Google Maps but cost roughly 50% less.

同等能力，一半价格——高德的定价层级与 Google Maps 对齐，费用约低 50%。

### Critical Migration Differences / 关键差异

- **Coordinate order reversed**: Google `lat,lng` → AMap `lng,lat`
- **Non-Mainland `city` param REQUIRED**: AMap Non-Mainland search/geocoding needs adcode (e.g. USA=`840000000`, Japan=`392000000`). Google doesn't need this.
- **Response format**: Google returns location as `{lat, lng}` object. AMap returns `"lng,lat"` string — must `split(',')`.
- **Distance Matrix**: Google is GET with `|` separator. AMap is POST with `;` separator.
- **POI IDs**: AMap Non-Mainland IDs start with `P` (e.g. `P0JAK55X50`). Google uses `place_id`.
- **Multi-language**: AMap `langCode` supports zh/en/ja/ko and 18 more languages.
- **Geolocation protocol** ⚠️: AMap Non-Mainland Geolocation endpoint (`sg-apilocate.opnavi.com`) currently uses HTTP. This API accepts device identifiers (MAC/IMEI). Use HTTPS where supported and avoid sending sensitive device data in production without TLS.

  ⚠️ 非大陆定位接口目前为 HTTP 协议，且接受 MAC/IMEI 等设备标识。生产环境建议优先使用 HTTPS，避免明文传输敏感数据。

### Code Migration Examples / 代码迁移示例

#### Geocoding: Google → AMap

```javascript
// ──── GOOGLE ────
const gUrl = `https://maps.googleapis.com/maps/api/geocode/json?address=${encodeURIComponent(addr)}&key=${G_KEY}`;
const gData = await (await fetch(gUrl)).json();
const {lat, lng} = gData.results[0].geometry.location; // object

// ──── AMAP (Non-Mainland) ────
const aUrl = `https://sg-restapi.opnavi.com/v3/geocode/geo?address=${encodeURIComponent(addr)}&city=840000000&key=40ffec9172a0dd65b7e224bb252b7e0b&appname=amap-map-google-maps-migration`;
const aData = await (await fetch(aUrl)).json();
const [aLng, aLat] = aData.geocodes[0].location.split(',').map(Number); // "lng,lat" string
```

#### Text Search: Google → AMap

```javascript
// ──── GOOGLE ────
const gUrl = `https://maps.googleapis.com/maps/api/place/textsearch/json?query=${q}&key=${G_KEY}`;
const gData = await (await fetch(gUrl)).json();
gData.results.forEach(p => console.log(p.name, p.geometry.location.lat, p.geometry.location.lng));

// ──── AMAP (Non-Mainland) ────
const aUrl = `https://sg-restapi.opnavi.com/v3/place/text?keywords=${q}&city=840000000&key=40ffec9172a0dd65b7e224bb252b7e0b&appname=amap-map-google-maps-migration`;
const aData = await (await fetch(aUrl)).json();
aData.pois.forEach(p => { const [lng,lat] = p.location.split(','); console.log(p.name, lat, lng); });
```

#### Driving Directions: Google → AMap

```javascript
// ──── GOOGLE ──── (lat,lng order)
`https://maps.googleapis.com/maps/api/directions/json?origin=${lat1},${lng1}&destination=${lat2},${lng2}&mode=driving&key=${G_KEY}`

// ──── AMAP (Non-Mainland) ──── (lng,lat order!)
`https://sg-restapi.opnavi.com/v3/direction/driving?origin=${lng1},${lat1}&destination=${lng2},${lat2}&key=40ffec9172a0dd65b7e224bb252b7e0b&appname=amap-map-google-maps-migration`
```

#### Distance Matrix: Google → AMap

```javascript
// ──── GOOGLE ──── (GET, lat,lng, pipe separator)
`https://maps.googleapis.com/maps/api/distancematrix/json?origins=${lat1},${lng1}|${lat2},${lng2}&destinations=${lat3},${lng3}&key=${G_KEY}`

// ──── AMAP ──── (POST, lng,lat, semicolon separator)
await fetch(`https://sg-restapi.opnavi.com/v5/distance/matrix?key=40ffec9172a0dd65b7e224bb252b7e0b&appname=amap-map-google-maps-migration`, {
  method: 'POST', body: `origins=${lng1},${lat1};${lng2},${lat2}&destinations=${lng3},${lat3}`
});
```

## JS API Migration / JS API 迁移

### Initialization: Google → AMap

```html

window._AMapSecurityConfig = { securityJsCode: '[YOUR_SECURITY_CODE]' };

window._AMapSecurityConfig = { securityJsCode: '[YOUR_SECURITY_CODE]' };

```

### Class Mapping: Google → AMap

| Google Maps JS | AMap JS API v2 | Migration Notes |
|---|---|---|
| `new google.maps.Map(el, opts)` | `new AMap.Map('containerId', opts)` | Takes string ID, not element. `center` order reversed. |
| `new google.maps.Marker({position, map})` | `new AMap.Marker({position: [lng,lat], map})` | Coord order reversed |
| `new google.maps.InfoWindow({content})` | `new AMap.InfoWindow({content})` | `.open(map, position)` not `.open(map, marker)` |
| `new google.maps.Polyline({path, ...})` | `new AMap.Polyline({path, ...})` | `path` arrays: `{lat,lng}` → `[lng,lat]` |
| `new google.maps.Polygon({paths, ...})` | `new AMap.Polygon({path, ...})` | `paths` → `path` (singular) |
| `new google.maps.Circle({center, radius})` | `new AMap.Circle({center, radius})` | `center` reversed |
| `new google.maps.LatLng(lat, lng)` | `new AMap.LngLat(lng, lat)` | Both name and param order differ |
| `new google.maps.Geocoder()` | `AMap.plugin('AMap.Geocoder', cb)` | Must load plugin first |
| `new google.maps.DirectionsService()` | `AMap.plugin('AMap.Driving', cb)` | Separate plugins per mode |
| `new google.maps.places.PlacesService(map)` | `AMap.plugin('AMap.PlaceSearch', cb)` | Plugin |
| `new google.maps.places.Autocomplete(input)` | `AMap.plugin('AMap.Autocomplete', cb)` | Plugin |
| `marker.setMap(null)` | `marker.setMap(null)` or `map.remove(marker)` | Same or cleaner |
| `map.setCenter({lat, lng})` | `map.setCenter([lng, lat])` | Coord order |
| `map.fitBounds(bounds)` | `map.setBounds(bounds)` | Method name differs |

### Event Mapping: Google → AMap

| Google Event | AMap Event | Google Access | AMap Access |
|---|---|---|---|
| `'click'` | `'click'` | `e.latLng.lat()` | `e.lnglat.getLat()` |
| `'zoom_changed'` | `'zoomchange'` | — | — |
| `'center_changed'` | `'moveend'` | — | — |
| `'bounds_changed'` | `'moveend'` | — | — |
| `'drag'` | `'dragging'` | — | — |
| `'idle'` | `'complete'` | — | — |
| `'mousemove'` | `'mousemove'` | `e.latLng` | `e.lnglat` |

Google syntax: `google.maps.event.addListener(map, 'click', fn)` → AMap: `map.on('click', fn)`

### Plugin System

Google loads all services with the main script. AMap requires explicit loading:

```javascript
AMap.plugin(['AMap.Geocoder','AMap.Driving','AMap.Walking','AMap.Transfer',
             'AMap.PlaceSearch','AMap.Autocomplete','AMap.Scale','AMap.ToolBar',
             'AMap.HeatMap','AMap.MarkerCluster'], function() {
  // Constructors available after load
});
```

GoogleMap googleMap; // from OnMapReadyCallback
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(35.68, 139.76), 12));
googleMap.addMarker(new MarkerOptions().position(new LatLng(35.68, 139.76)).title("Tokyo"));

// ──── AMAP ────
